Heavy Metals
Term · Environment · MLC-T-ENV-013102
1. Metallic elements with high atomic weights; (e.g., mercury, chromium, cadmium, arsenic, and lead); can damage living things at low concentrations and tend to accumulate in the food chain.
2. A group of highly toxic metals that are generally harmful to plants and animals.
3. Metallic elements with high atomic weights, e g, mercury, chromium, cadmium, arsenic, and lead. They can damage living things at low concentrations and tend to accumulate in the food chain.
4. Any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations.
5. Metallic elements with high atomic weights, such as, mercury chromium cadmium, arsenic, and lead. Even at low levels these metals can damage living things. They do not break down or decompose and tend to build up in plants, animals, and people causing health concerns.
6. Metallic elements with high atomic weights, e.g., mercury, chromium, cadmium, arsenic, and lead; can damage living things at low concentrations.
7. Metallic elements, such as mercury, lead, nickel, zinc, and cadmium, that are of environmental concern because they do not degrade over time. Although many are necessary nutrients, they are sometimes magnified in the food chain and in high concentrations can be toxic to life.
8. Metals such as lead, chromium, copper, and cobalt that can be toxic at relatively low concentrations.
9. Metals such as chromium, cadmium, mercury, and lead.
10. Metallic elements with high atomic weights such as mercury, chromium, cadmium, arsenic, and lead. They can damage living organisms at low concentrations.
11. A metal having a specific gravity of 5.0 or greater. Heavy metals are generally toxic to organisms in relatively low concentrations, and tend to accumulate in the food web. Examples include arsenic, cadmium, chromium, lead, and mercury.
12. Metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations.
13. All uranium, plutonium, or thorium placed into a nuclear reactor.
